Instructions

Implementation Reference

• src/index.ts:1189-1206 (handler)

  MCP tool handler that extracts parameters, calls SentryAPIClient.listErrorEventsInProject, and formats the response as text content listing error events.

  case "sentry_list_error_events_in_project": {
    if (!apiClient) {
      throw new Error("Sentry API client not initialized. Provide auth token.");
    }
    
    const { projectSlug, limit = 50, query } = args as any;
    const events = await apiClient.listErrorEventsInProject(projectSlug, { limit, query });
    
    return {
      content: [
        {
          type: "text",
          text: `Found ${events.length} error events in project ${projectSlug}:\n` +
            events.map((e: any) => `- ${e.title} (${e.eventID}) - ${e.dateCreated}`).join('\n'),
        },
      ],
    };
  }

• src/index.ts:548-569 (schema)

  Tool schema definition including name, description, and input schema with projectSlug required, optional limit and query.

    name: "sentry_list_error_events_in_project",
    description: "List error events from a specific Sentry project. View recent errors, frequency patterns and occurrence timestamps.",
    inputSchema: {
      type: "object",
      properties: {
        projectSlug: {
          type: "string",
          description: "Project slug/identifier",
        },
        limit: {
          type: "number",
          description: "Number of events to return",
          default: 50,
        },
        query: {
          type: "string",
          description: "Search query",
        },
      },
      required: ["projectSlug"],
    },
  },

• src/sentry-api-client.ts:195-198 (helper)

  Core implementation in SentryAPIClient that constructs and sends HTTP request to Sentry API endpoint for project events using the provided parameters.

  async listErrorEventsInProject(projectSlug: string, params?: any) {
    const queryParams = params ? '?' + new URLSearchParams(params).toString() : '';
    return this.request(`/projects/${this.org}/${projectSlug}/events/${queryParams}`);
  }
